Description
adjustUnextendedSP() determines a wrong value for raw_unextendedSP. It uses the FP which basically pops the frame, so we end up in the wrong frame.
This causes errors like JDK-8339772.

[jdk23u, jdk21u-dev, jdk17u-dev] Fix Request The SA shouldn't use the wrong unextendedSP in those JDK releases, either. The fix only touches one PPC64 specific file, applies cleanly and tier 1-4 have passed.
